    Retinoblastoma is the most common pediatric intraocular malignancy, yet its aggressive proliferative mechanisms remain poorly understood.

  • 2

    Single-cell RNA sequencing identified 10 retinal cell types, highlighting specific proliferative subpopulations in retinoblastoma.

  • 3

    BIRC5 was found to be overexpressed in 93.7% of highly proliferative MKI67⁺ cells, indicating its role in malignant proliferation.

  • 4

    BIRC5 overexpression enhanced cell proliferation, invasion, and migration while inhibiting checkpoint control mechanisms.

  • 5

    Knockdown of BIRC5 led to G1 cell cycle arrest and increased apoptosis, suggesting its potential as a therapeutic target in retinoblastoma.
